Liam has 9/10 gallon of paint for painting the bird houses he sells at the craft fair each birdhouse requires 1/20 gallon of pai

Rina8888 [55]

So to get the fractions easier to understand you need to put them on the same level you are on. So change the 9/10 gallons to 18/20 ( this makes them easier to deal with the 1/20)
so put 1/20 into 18/20. Liam can paint 18 bird houses.

MATH HELP 10 PTS

Lesechka [4]

Answer:

The width is 5 and the length is 11

Step-by-step explanation:

The formula for perimeter is

P = 2(l+w)

We know the perimeter is 32

32 = 2 (l+w)

Divide each side by 2

32/2 = 2(l+w)

16 = l+w

We know the length is 6 longer than the width

l = w+6

16 = w+6+w

Combine like terms

16 = 2w+6

Subtract 6 from each side

16-6 = 2w+6-6

10 = 2w

Divide by 2

10/2 = 2w/2

5 =w

The length is

l = w+6

5+6 = 11

Solve the quadratic equation x2 - x = 30 by completing the square

kap26 [50]

Answer:

Step-by-step explanation:

Given

x² - x = 30

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- $\frac{1}{2}$ )x + $\frac{1}{4}$ = 30 + $\frac{1}{4}$

(x - $\frac{1}{2}$ )² = $\frac{121}{4}$

Take the square root of both sides

x - $\frac{1}{2}$ = ± $\sqrt{\frac{121}{4} }$ = ± $\frac{11}{2}$

Add $\frac{1}{2}$ to both sides

x = $\frac{1}{2}$ ± $\frac{11}{2}$ , thus

x = $\frac{1}{2}$ - $\frac{11}{2}$ = - 5

x = $\frac{1}{2}$ + $\frac{11}{2}$ = 6
